I looked for about six pages back and didn't see this mentioned, which is a little surprising unless it's just me. I've noticed in my tavern that the actual damage per second of the lightning tower is twice its listed value when you look at its stats, and it seems to also be off by half in combat in both insane and nightmare, with or without buff beams. (I can't be sure since there's no convenient dps number floating above their heads, but it definitely seems to hit much harder than its listed number says it should, which I don't mind. I hope it's just the listed number that is off!)
